80299313 ÷ 663 
We're looking to find how many times 663 goes into 80299313.

Step 1:
663 goes into 8 0 times with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 663

On to step 2:
663 can be fit into 80 0 times, resulting in a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (2) of the dividend behind the 80 and repeat the process: 802 / 663

Let's proceed to step 3:
The number 663 fits into 802 1 times, leaving a remainder of 139.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 663 away from 802, we end up with 139.
Take the next digit (9) from the dividend and append it to 139, then repeat: 1399 / 663

Let's proceed to step 4:
663 can be fit into 1399 2 times, resulting in a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we take 1326 away from 1399, we end up with 73.
Bring next digit (9) of the dividend behind the 73 and repeat the process: 739 / 663

Advancing to step 5:
739 divided by 663 is 1 with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Subtracting 663 from 739 leaves us with 76.
Take the next digit (3) from the dividend and append it to 76, then repeat: 763 / 663

Going ahead to step 6:
663 can be fit into 763 1 times, resulting in a remainder of 100.
Write down 1 as next digit of the result. 
Result so far: 1211.0
If we take 663 away from 763, we end up with 100.
Fetch the next digit (1) from the dividend, attach it to 100 and continue: 1001 / 663

Advancing to step 7:
The number 663 fits into 1001 1 times, leaving a remainder of 338.
Use 1 as the next digit of our solution. 
Result so far: 12111.0
The remainder is 338 after subtracting 663 from 1001.
Bring next digit (3) of the dividend behind the 338 and repeat the process: 3383 / 663

Step 8:
When dividing 3383 by 663, we get 5 with a remainder of 68.
The next digit of our result is 5. 
Result so far: 121115.0
If we take 3315 away from 3383, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 9:
680 divided by 663 is 1 with a remainder of 17.
The next digit of our result is 1. 
Result so far: 121115.1
The remainder is 17 after subtracting 663 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 10:
663 can be fit into 170 0 times, resulting in a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 121115.1
Deduct 0 from 170 and we're left with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 11:
1700 divided by 663 is 2 with a remainder of 374.
Write down 2 as next digit of the result. 
Result so far: 121115.102
The remainder is 374 after subtracting 1326 from 1700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3740, and continue the process.

Let's proceed to step 12:
663 goes into 3740 5 times with a remainder of 425.
Record the quotient 5 as the next digit in the result. 
Result so far: 121115.1025
The remainder is 425 after subtracting 3315 from 3740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

On to step 13:
The number 663 fits into 4250 6 times, leaving a remainder of 272.
Write down 6 as next digit of the result. 
Result so far: 121115.10256
Subtract 3978 from 4250 to get 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Advancing to step 14:
663 can be fit into 2720 4 times, resulting in a remainder of 68.
The number 4 becomes the next digit in our result. 
Result so far: 121115.102564
The remainder is 68 after subtracting 2652 from 2720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Advancing to step 15:
The number 663 fits into 680 1 times, leaving a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 121115.1025641
The remainder is 17 after subtracting 663 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 16:
The number 663 fits into 170 0 times, leaving a remainder of 170.
The next digit of our result is 0. 
Result so far: 121115.1025641
The remainder is 170 after subtracting 0 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

The final outcome is 121115.1025641, with a leftover of 1.7e-07.
